Specification of Letters Patent.

Application filed September 8, 1909. Serial No. 516,719.

To all whom it may concern:

Be it known that I, EDMUND F. BEAU- MONT, a citizen of the United States, and resident of San Antonio, in the county of Bexar and State of Texas, haveinvented certain new and useful Improvements in Furnaces, of which the following is a specification.

The invention relates to automatic grateshaking mechanism and it has for its object the provision of means for transmitting motion from a movable member of the engine connected with the furnace to the grate-bars to agitate the latter, which means will be under control of the engineer so that he can regulate the operation of the same to meet the requirements of the fuel and combustion conditions of the fire in the furnace.

It consists in the novel construction, combination and arrangement of parts here inafter fully set forth, pointed out in the appended claims, and illustrated in the ac companying drawings.

While the mechanism will be described as applied to the furnace and engine of a locomotive, yet it can be applied to a stationary furnace provided with a suitable source of power.

In the drawings Figure 1 is a side elevation of mechanism embodying the invention. Figs. 2 and 3 are similar views respectively showing different modifications of the same.

Referring to Fig. 1 of the drawings, A designates the pivoted grate-bars having at their ends the arms 1 to which is loosely hinged the connecting-rod B by pins 2 passing through the rod and the slots 3 in the arms. The outer end of the connecting-rod, as at 1, is pivoted to the upper end of the lever C journaled at its lower end on the shaft D mounted in bearings 5 suitably placed in the frame of the engine. By means of a clutch-mechanism the lever can be locked on the shaft. This clutch-mechanism comprises the pin 6 slidable in guides 7 on the lever. The pin is normally pressed by the spring 8 toward the shaft to engage the hole 9 in the latter. By means of the handlever 10 pivoted to the main lever G and connected by the rod 11 with the pin 6, the latter can be moved against the action of the spring 8 to free the main lever from the shaft. A removable hand-bar E is pro vided, having at an end the socket 12 to fit the upper end of the lever C. On the shaft D is the crank-arm F having at its outer end the pin 13 slidable in the slot 14; in the link G. The upper end of the link, as at 15, is fulcrumed to the outer end of one of the members of the bell-crank H mounted in bearing 16 on the engine-frame. The outer end of the other member of the bell-crank is connected by the rod 17 with the controllinglever I hinged to the engine-frame. By means of this lever and the intermediate connections the link G can be adjusted on the pin 18. The lever is held in its adjustments by the hand-operated pawl 18 engaging the segmental rack 19. The lower end of the link G, as at 20, is hinged to the outer end of the reach-bar J, which is pivoted at its inner end, as at 21, to the arm K fast on the pin 22 of the rear driving wheel of the engine.

The operation of the mechanism shown in Fig. l is as follows: While the locomotive is traveling in either direction, the arm K oscillates the reach-arm J, which has a movement back and forthequal to the diameter of the circle described by the pin 21 around the axis of the driving-wheel. The oscillation of the reach-arm vibrates the link G on its fulcrum 15. As the pin 13 on the lower end of the crank-arm F is in the upper end of the slot 1 1 of the link opposite to the fulcrum 15, the link is in a neutral position so that no motion is imparted to the crankarm. Should it be desired to shake the grate, by operating the hand-lever 10 the pin 6 is permitted by the action of its spring to engage the hole 9 in the shaft D to lock the lever C fast on the latter, and by means of the controlling-lever I, the rod- 17 and the bell-crank H the link G is raised on the pin 13. This adjustment of the link, which may be more or less, separates the pin 13 from the fulcrum 15, so that the vibration of the link will be transmitted to the crankarm, which rocks the shaft D. As the lever C has been locked on the shaft the former is vibrated and oscillates the connecting-rod B, which rocks or shakes the grate-bars A. The sliding pivotal connections between the grate-bars and the connecting-rod permit the latter to move up and down slightly to accommodate the movement of the lever C. By adjusting the link G on the pin 13 by means of the controlling-arm I the desired degree of agitation of the grate can be secured. When the grate has been sufficiently shaken, the link G is dropped on the pin 13 to its neu'tralposition and, if need be, the

pin 6 of the clutch-mechanism is disengaged from the hole 9 of the shaft -D, which unlocks the arm C from the latter. Should it curedthe connecting-rod B can be moved g 7 back and forth ,to rock the grate-bars by anua ro er- V )Inthe construct-ion shown in vFig. the grate-bars A are pivoted to the connectingrod BQ'and the latter is hinged to the handlever C, In this instance the connectingrod is connected with the upper end of the "arm 1C separate and distinct from the handlever Ca The arm C is fjournaledon the shaft D mountedin bearmg on the engineframe' A clutch 6 is provided for locking 1 the arm O fast on the shaft. On the shaft 1 is the crank-arm having at its lower end a pin slidablein the slotof the link Gr fulcrumed fat-its upper end to one -of the 'members of the bell-crank H.

The other member of the bell-crank is connected by a rod with the controlling lover I, which is provided with a'handpawl mechanism to hold in its adjustments. The lowerend of the link is connectedby .t-he reach-rod J 7 with the arm K fasten the, pin of thedrivewheel. The operation of this modified con- Struction isas follows: Through its connection with the arm K the link G is oscillated while the locomotive moves in either direction. By raising the link, by moving the bell-crank'I-I through the operation of the controlling lever I andthe intermediate connections, an oscillation is given to the crank-arm F, which rocks theshaft D.

- 1 The lever Q having been locked on the shaft D by the clutch6 the lever is vibrated by the rocking .of the shaft and oscillates the connecting-rod B, which in turn rocks the grateibars A. The extent tov which ;the

* grate-bars will beagitated can be regulated by adjusting the link G on the pin at the lower end of the crank-arm -F. When it is desired to stop the shaking of the grate the link G ,is dropped .to its neutral position by operating the controlling lever I :Iand the Clutch 6* is operated to unlock the lever C from the shaft B. When it is desired to shake the grate in'this instance when the locomotive is at rest, it can ,betlonegby ap-' 'plying manual power to the lever O, the

V clutchfi havi-ng been operated to release the lever C from the shaft D.

It {is to befobserved that in theconstructions "sh n Figs-"1 '2 the Op ra i mechanism is located on the side of the locomotive and the'motion is derived from the v rear drive-wheel.

In the construction shown in Fig, 3 the grate-bars A? are pivoted to the connectingrod "B hin ed at its forward end to the hand-lever 6 The connecting-rod is connected to the arm C journaled on the shaft T D? mounted in bearing on the frame of the locomotive. A clutch 6 operates to lock the arm 0* fast on the shaft D". t On the latter risihe crank-arm F having at its lower end a pin engaging the slotin the link G The latter at its upper end is fulcrumejd to one of the members of the bell-crank H the other member of which is connected by a rod with the controlling lever I provided with a hand-pawl mechanism to hold it in its adjustments. The lower end of the link is connected by the reach-rod J 2 with the strap .K on the eccentric K7?" fast on the axle of the driving wheels ,beneath the boiler. The operation of the modification in this last instance isas follows: When the. locomotive is traveling in either direction, by the rotation of the eccentric K an oscillatory motion is imparted to the strap K which in turn oscillates the reach-rod J and thereby vibrates the link G 7. As shown in the .drawing, the link is in its neutral position. By raising thelink through the operation of the controlling lever I onthe pin atthe lower end of the crank-arm F the latter is vibrated and a rocking motion is imparted to the shaft D. The lever C having been locked on the shaft I) by the clutch 6 it will also be rocked and will impart through the connecting-rod B a rocking movement to the grate-bars A3. By adjusting the linkon the pin at the lower end of the crank-arm any desired degree of agitation of the grate can be secured. When the lever C is unlocked from the shaft D thegrate can 'be agitated by applying manual power to the lever C. In this last modification the operative mechanism is ,mounted beneath the boiler instead of at "its side as in the. first two instances. a

While three different embodimentsof the invention have been described, yetv others might be devised involving the principles employed; also, the mechanism can be used with stationary furnaces as well as with those of a locomotive, a suitable source of power being (provided;
